Hortensia

Description:

Flowering plant native to southern and eastern Asia. They are very common in local gardens in Galicia, Spain, and Portugal. In most species the flowers are white, but in some species (notably H. macrophylla), can be blue, red, pink, light purple, or dark purple. In these species the color is affected by the pH of the soil; acidic which can be taken up into hyperaccumulating plants. For H. macrophylla and H. serrata cultivars, the flower color can be determined by the relative acidity of the soil: an acidic soil (pH below 6) will usually produce flower color closer to blue, whereas an alkaline soil (pH above 6) will produce flowers more pink.
